DETAILED DESCRIPTION OF THE BEST MODES AND PREFERRED EMBODIMENTS OF THEINVENTION

Hydrogen absorption within reversible metal hydrides (including metalalloys) may be used as hydrogen storage devices. Applicant has found, bytesting, that adsorbing hydrogen (as by destabilizing hydrogen bonds)from such metal hydrides at reasonable temperatures and with reasonableenergy expenditures may be best accomplished by very finely controlledheating. It has been found that this may provide an economical return ofgreater than about 5% (by weight) of hydrogen from a storage medium,with minimal energy consumption and system weight.

It is desirable to increase the absorbed hydrogen mass within the metalhydride while simultaneously reducing the energy required to release thehydrogen. Applicant has found that metallic alloys and metallic cappinglayers, along with metal-doped chemical and organic carriers, areexcellent storage media for hydrogen. However, one primary obstacle toreleasing hydrogen, from such storage media, is a need for heat, sincedecomposition temperatures are typically greater than 200° C.

Applicant has determined that laser heating of magnesium hydride is onepreferred method for extracting hydrogen, with available technology andminimal energy cost. Employment of at least one laser diode, usingpulsed-power, preferably provides ample heating of magnesium hydride torelease hydrogen, as shown in FIG. 1. Applicant has found, includingthrough experimentation, that less than about 80 continuous watts areneeded to heat enough magnesium hydride to release about 10 lbs (4.5 kg)of hydrogen at rates of up to about 2 lbs (0.9 kg) per hour. Such ratesof hydrogen may theoretically provide internal combustion, hybrid, andhydrogen-fuel-cell vehicles a range in excess of about 200 miles, whileadding less than about 330 lbs (150 kg) and about 6.3 cubic feet (0.18cubic meters) or about 47 gallons (178 liters). Conventional CD (compactdisk) motors, along with modified laser circuitry, may preferably exposeat least one magnesium hydride disk to at least one laser beam atrotations of up to about 24,000 rpm.

FIG. 1 shows a partial side view of at least one hydride disk 110,illustrating release of hydrogen gas 150 preferably by laser heating,according to a preferred embodiment of the present invention. Hydrogenenergy system 100 preferably comprises embodiment 101, as shown. Hydridedisk 110 preferably comprises at least one metal hydride, preferablysubstantially magnesium hydride. As discussed herein, concentration ofhydrogen, stored in hydride disk 110, preferably should be greater thanabout 5% by weight, for economical efficiency. Magnesium hydridetheoretically maximally stores about 7.6% hydrogen by weight. Uponreading this specification, those skilled in the art will now appreciatethat, under appropriate circumstances, considering such things as thenavailable forms of metal hydride, abilities to place such forms in arotatable “disk” shape structure for use with controlled laser heating,etc., other “disks” than unitary and/or complete “disks”, suchsegmented, liquid, or non-unitary “disks”, etc., may suffice.

Heating of hydride disk 110 preferably comprises localized heating byphotonic excitation using at least one coherent light source 160, asshown. Coherent light source 160 preferably comprises at least onesemiconductor laser diode 165, as shown. Upon reading thisspecification, those skilled in the art will now appreciate that, underappropriate circumstances, considering such things as then availablelight sources, cost, used hydrogen storage medium, etc., other lightsources, such as focused sunlight, phosphorescent light, biochemicallight, etc., may suffice. Semiconductor laser diode 165 preferablyproduces a beam of coherent light 170, as shown, preferably betweenabout 530 nm and about 1700 nm in wavelength, preferably about 784 nm inwavelength and with preferably between about 200 mW and about 2000 mW ofpower, preferably about 200 mW of power. Upon reading thisspecification, those skilled in the art will now appreciate that, underappropriate circumstances, considering such things as then availablelasers, cost, used hydrogen storage medium, etc., other wavelengths ofcoherent light, such as other infrared wavelengths, visible spectrum,ultraviolet, etc., may suffice. To assist keeping semiconductor laserdiode 165 from overheating, power is preferably pulsed instead ofcontinuous.

Preferably, as coherent light 170 adsorbs hydrogen gas 150, size ofhydride disk 110 will preferably initially increase due to thermalexpansion and then preferably reduce to pre-hydrogenated volumes. Somesmall amount of hydrogen movement from higher concentration to lowerconcentration theoretically can be expected in hydride disk 110 afteradsorption of a particular track; but applicant has found such movementto be inconsequential in most circumstances.

Preferably, coherent light source 160 further comprises at least onedefocusing lens 162, as shown. Defocusing lens 162 preferably altersfocus of coherent light 170 to form at least one defocused laser beam168, as shown. Defocused laser beam 168 preferably comprises at leastone beam radius 136 at surface 140, as shown. Beam radius 136 preferablyranges between about 10 nm and about 2 mm, preferably about 15 nm, asshown. Clearance 174 between defocusing lens 162 and surface 140preferably is about two millimeters, as shown, assisting protectingdefocusing lens 162 from impacting surface 140 due to slightdeformations that may occur in surface 140.

Applicant has determined, including by testing, that decomposition ofmagnesium hydride using at least one surface temperature of about 390°C., in a vacuum at about −5 bar, is reached within about 10 ns withenough conductivity to release 100% of stored hydrogen (up to about 7.6wt %) within beam radius 136, to a depth of about 20 micrometers. Atleast one maximum effective decomposition distance 145 comprising about½ mm, the temperature decreases to about 280° C., dropping release ofstored hydrogen to about 39.5% of maximum (up to about 3 wt %). Sincemagnesium typically melts at about 650° C., applicant has found that asurface temperature of about 390° C. (60% of melting temperature)roughly minimizes adiabatic evaporation of magnesium.

Coherent light source 160 preferably rides on at least one rail 175,preferably moving radially, near at least one surface 140 of hydridedisk 110, as shown. Hydride disk 110 preferably spins about a centralaxis 215 (see FIG. 2), preferably positioning surface 140 for defocusedlaser beam 168 to induce heating, as shown.

Absorptivity to infrared radiation is inversely proportional to thermalconductivity. Applicant has determined that, unlike for magnesium,thermal conductivity of magnesium hydride increases with risingtemperature, attributable to radiation and “the Smoluchowski effect”(described in Marian Smoluchowski's paper ‘Zur kinetischen Theorie derBrownshen molekular Bewegung and der Suspensionen’ in Annalen derPhysik, 21, 1906, 756-780). Heat capacity is also greater in magnesiumhydride as compared to magnesium. Magnesium has a specific heat capacityof about 1050 J/(kg·K) (at 298 K) and the specific heat capacity ofmagnesium hydride is about 1440 J/(kg·K) (at 298 K). Further,magnesium's thermal conductivity is about 156 W/(mk), while magnesiumhydride's thermal conductivity is about 6 W/(mk).

One formula, as determined by applicant, for thermal diffusivity (a) (afactor in the depth of thermal penetration), using thermal conductivity(λ), density (ρ), and specific heat (c) is:

a=λ/ρc

Calculating thermal diffusivity for magnesium hydride gives:

a=(6 W/(m·K)/(0.001450 kg/m³×1440 J/(kg·K))=2.87×10⁶ J/(m³·K)

Using this calculation of thermal diffusivity for magnesium hydride,applicant estimates thermal penetration (Z), based on a pulse time of115 ns at 4× rotational speeds and 19 ns at 48× rotational speeds, as:

Z=√(4·a·t)=36334 nm at 4×(0.036 mm)

Z=√(4·a·t)=14769 nm at 48×(0.015 mm)

Estimated thermal penetration is inadequate for release of all storedhydrogen in hydride disk 110 by a factor of about 30, for a 1 mmthickness. Applicant has determined, however, that since magnesiumhydride has a refractive index of about 1.96, which provides about 80%transparency, that optical penetration may aid in increasing release ofstored hydrogen. Applicant has found that, through modification of powerdensity to find at least one optimal power setting and beam radius 136,maximum effective decomposition distance 145, comprising about ½ mm, maybe reached, as shown. In order to instigate hydrogen adsorptionsubstantially through thickness 144 of hydride disk 110, preferably,defocused laser beam 168 may also be incident upon opposing surface 142.

Power density, mathematically defined as:

E=q/π·r ²

where q is beam power and r is beam radius, determines peak temperature,near surface 140, and thermal interaction at interface 172 of hydridedisk 110 and defocused laser beam 168. Applicant has found that a powerdensity capable of adsorbing hydrogen from magnesium hydride need onlybe concerned with the melting point of magnesium.

For magnesium hydride, coherent light source 160 preferably produces atleast one temperature profile 130 in hydride disk 110, due to thermalinteraction at interface 172, as shown. Temperature profile 130preferably ranges from about 390° C., near surface 140, to about 280° C.at maximum effective decomposition distance 145, as shown.

Applicant has found by testing that, after the course of repeatedhydrogen absorption and desorption cycles, the fabricated disks appearlose the ability to absorb hydrogen to the full extent (0.345 wt %)initially noted when the disks were new. Analysis of the disks indicatedthat contaminants had blocked interstitial spaces and eventually coatedareas along the surface of the disks. These contaminants might beconsidered (theoretically) to be related to the lack of 100% purity andmay be to be an inevitable consequence of the hydrogen source.

In testing and analysis of the previously mentioned lower-capacitydisks, there was evidence of deuterium in the form of observed Time ofFlight (“ToF”) hydrogen deuterium (“HD”) signals which were not evidentin new disks. Time of Flight does not provide quantitative analysis, andtesting did identify the isotopes of hydrogen. A Secondary Ion MassSpectrometry (SIMS) study may be necessary to determine evidence ofincreased concentration with each absorption and desorption cycle.

The evidence of detectable amounts of deuterium in desorbed disks maytheoretically be explained by the stable, but larger structure of the HDmolecule, along with its permanent dipole moment. These characteristicsmay explain limited desorption of deuterium from the medium. Reducingthe laser pulse length into the tens of femtoseconds would increasephoton absorption by this molecule and potentially increase desorption.However, this approach may not reduce the general rise in contaminationby other elements.

An explanation of the contamination by deuterium is inconclusive. Thepredominant theory is that the molecules of HD and D₂ and even MgD₂ aremore stable, individually and within the metal lattice, to theparticular wavelengths and energy densities selected for desorption ofH₂ from Mg₂NiH₄+MgH₂. Over multiple cycles (using this theory), theconcentration of deuterium rises in the material and reduces therecharging capability.

According to a less predominant theory, it may be suspected that atransmutation may occur due to: (1) the high degree of ionizationafforded within the beam channels and (2) the fact that the molecularions entering into the beam channels are subjected to intense vibrationand oscillation in the presence of a nano-scale level electrostatic iontrap with increasing potentials. Support for this less predominanttheory may be found in: (1) occasions of thermal run-away in whichunexplained increases in temperature are clearly detected and (2) thefailure of the material to return to ambient temperature within thetimeframe expected for the power density and EM pulse directed at thematerial.

FIG. 2 shows a cutaway perspective view, illustrating at least onepreferred disk player 210, according to the preferred embodiment ofFIG. 1. As shown, disk player 210 preferably comprises at least onespinning motor 230, coherent light source 160 and disk changingmechanics. Such disk changing mechanics preferably accept at least onehydride disk 110, preferably move such at least one hydride disk 110 tospinning motor, and preferably remove such at least one hydride disk110, once expended, from disk player 210. Spinning motor 230 preferablyspins hydride disk 110 to achieve at least one linear motion of up toabout 63 meters per second, preferably while coherent light source 160liberates hydrogen gas 150 from hydride disk 110, as shown. Disk player210 preferably operates under vacuum between about −1 torr to about −5ton. Such vacuum preferably serves to evacuate liberated hydrogen gas150, as shown in FIG. 1, and preferably maintains a neutral atmospherearound hydride disk 110.

At least one control circuit 220, as shown, preferably adjusts speed ofspinning motor 230, preferably moves coherent light source 160 on rail175, and preferably adjusts power output of coherent light source 160(at least embodying herein at least one photonic exciter structured andarranged to photonically excite such at least one hydrogen storer toassist release of the stored hydrogen from such at least one hydrogenstorer) to preferably optimize release of hydrogen gas 150. Output ofhydrogen gas 150 is preferably optimized to demand for hydrogen gas 150from at least one hydrogen-driven device 830 (see discussion relating toFIG. 8).

Applicant has determined that disk player 210 may preferably bereconfigured from existing compact disc writer (CD-R) technology.Applicant adapted at least one CD writer drive (“Iomega model 52x” CDRWdrive) to adsorb stored hydrogen from hydride disk 110. In order toadapt such at least one CD writer to use hydride disk 110, at least onecontrol circuit 220, as shown, preferably bypasses internal feedbackcontrols of such at least one CD writer drive. Rather than relying onfeedback information, control circuit 220 preferably uses directmanipulation of controlled components of disk player 210, preferablyallowing precise control. Further, internal laser of CD writerpreferably may be used provided such laser fulfills requirements givenfor semiconductor laser diode 165.

Manufacturing Magnesium Hydride Disks

FIG. 3 shows a top view, illustrating at least one disk 315 according toembodiment 101 of FIG. 1. Such at least one disk 315 is preferablyformed by cutting from at least one sheet preferably comprising at leastone material capable of absorbing hydrogen, preferably metal, preferablymade substantially of magnesium, preferably AZ31B (availablecommercially). Upon reading this specification, those skilled in the artwill appreciate that, under appropriate circumstances, considering suchthings as available materials, economics, stored hydrogen density, etc.other materials capable of absorbing hydrogen, such as other metals,plastics, glass, etc., may suffice. Upon reading this specification,those skilled in the art will appreciate that, under appropriatecircumstances, considering such things as safety, economics, materialsused, etc. other disk formation methods, such as using injection molds,machining, laser cutting, etc., may suffice.

Disk 315 is preferably cut using at least one water cutter, alternatelypreferably using at least one stamp cutter. Disk 315 preferably is aboutone millimeter thick. Diameter 370 of disk 315 is cut preferably tobetween about 50 mm and about 150 mm, preferably about 120 mm. A centerhole 360 is preferably cut in disk 315, preferably between about fivemillimeters and about 15 millimeters in diameter, preferably about 15millimeters. Preferably, center hole 360 allows disk 315 to be centeredfor stable spinning. Disk 315 preferably comprises at least one ring 365concentric to center hole 360 (at least embodying herein wherein such atleast one hydrogen storer comprises at least one central spin axislocator structured and arranged to locate at least one central spin axisof such at least one disk) preferably providing at least one frictiongrippable surface preferably to allow application of rotational torqueto spin disk 315, as shown (this arrangement at least embodying hereinwherein such at least one disk comprises at least one spinner motorgripper capable of being gripped by at least one motor driven spinner).

FIG. 4A shows a side view of preferred disk 315, illustrating surfacepreparation, according to embodiment 101 of FIG. 1. Preferably, afterfabrication, oxidization layers, vapor deposits and other physicalobstructions to hydrogenation must be removed from disk 315. Surfaces346 of disk 315 preferably may be smoothed to a mirror-like finish withirregularities of preferably less than two micrometers whileincorporating small amounts of hydrogenation catalysts. Additionally,disk 315 preferably is structurally balanced so, when spun, surfaces 346have minimal wobbling. Irregularities of surfaces 346 may be distorted,by the addition of hydrogen gas 150, up to approximately 2½ micrometersas disk 315 expands.

Disk 315 preferably is lightly sanded with titanium oxide to removesurface oxidation. Disk 315 preferably is then washed with 2% HF toremove bulk oxides and then preferably with dilute pepsin/HCL cleaningsolution to remove residual sub-oxides. A plurality of such disks 315are preferably stacked on at least one spindle 345 with at least onestainless steel washer 520, as shown in FIG. 5, between each disk 315.Dimensions of stainless steel washer 520 preferably comprise about 15.3mm in inner diameter, about 18 mm in outer diameter, and about fourmillimeters in thickness. Spindle 345 preferably comprises steel,preferably stainless steel. Spindle 345 preferably comprises a diameterof about 14.9 mm. Spindle 345 preferably is positioned in vacuum chamber310, as shown. At least one vacuum chamber 310 is preferably purged withnitrogen. Vacuum chamber 310 is brought to preferably about 0.7 ton(0.014 psi) (0.001 bar) for preferably about one hour. After about 1hour, the plurality of such disks 315, on spindle 345, preferably isrotated at about 18,000 rpm. At least one spray nozzle 330, preferablydesigned for blasting at least one powder 340, preferably is at a fixeddistance from disk 315, as shown. Powder 340 preferably comprises nickelpowder, comprising a particle-size range of preferably about 2.6micrometers to about 3.3 micrometers, preferably nickel powdercommercially available as “Inco Type 287”. Powder 340 is preferablyblasted onto disk 315, as shown, at about 50 psi preferably using argongas. Disk 315 preferably is subsequently sandblasted with progressivelysmaller 99.9+% nickel particles, preferably from about −325 mesh toabout −500 mesh (American Elements CAS no. 7440-02-0) at preferablyabout 40 psi using preferably nitrogen gas.

FIG. 4B shows a side view of disk 315, illustrating introduction ofpreferred hydrogenation catalysts 440, according to embodiment 101 ofFIG. 1. Inside vacuum chamber 310, disk 315 is preferably furthertreated with hydrogenation catalysts 440, as shown. Hydrogenationcatalysts 440 preferably comprise at least one submicron powder 445, asshown. Hydrogenation catalysts 440 preferably are each applied forbetween about 10 minutes and about 15 minutes at preferably about 35psi. Each of preferably three submicron powders 445 preferably comprisesa purity of greater than about 99.999%. One Submicron powder 445preferably comprises 99.999+% nickel. Another submicron powder 445alternately preferably comprises 99.999+% palladium. Yet anothersubmicron powder 445 alternately preferably comprises 99.999+% titanium.Upon reading this specification, those skilled in the art will nowappreciate that, under appropriate circumstances, considering suchthings as then available materials, other catalyst technologies, cost,hydride material used, etc. other catalysts, such as other metals,plastics, resins, slurries, etc., may suffice.

Hydrogenation catalysts 440, preferably as described, preferably areserially applied such that application of all hydrogenation catalysts440 comprises between about 30 minutes and about 45 minutes. The amountof hydrogenation catalysts 440 used is insufficient for capping, andinstead preferably serves as a “door man” to preferably keep hydrogenmoving past outer layer of surfaces 346 where magnesium hydrideformation and buildup could prevent further absorption of hydrogen.Surface preparation and treatments with hydrogenation catalysts 440preferably provides necessary surface smoothness and preferablyimpregnates, through adhesion, a preferred amount of hydrogenationcatalysts 440 without significant ablation of surfaces 346.

Vacuum chamber 310 preferably is then returned to atmospheric pressure,preferably with nitrogen, and disk 315 preferably is removed to at leastone stainless-steel high-temperature pressure reactor 510, as shown inFIG. 5. Stainless-steel high-temperature pressure reactor 510 preferablyis nitrogen-purged with 0.1 torr on the evacuation cycle, preferablythrough at least two purging cycles to prepare for hydrogenation. Disk315 preferably is then ready for hydrogenation.

FIG. 5 shows a diagrammatic view of stainless-steel high-temperaturepressure reactor 510, illustrating preferred hydrogenation of disk 315on spindle 345, according to embodiment 101 of FIG. 1. At least oneheating element 560 preferably heats stainless-steel high-temperaturepressure reactor 510, as shown, from preferably about 20° C. topreferably about 350° C. The coefficient of thermal expansion (a) ofmagnesium is about 27·10⁻⁶/° C., which provides that disk 315 willexpand from a diameter of about 120 mm to about 121 mm when raised fromabout 20° C. to about 350° C. Because being raised from about 20° C. toabout 350° C. effects closing of diameter of central hole by as much asabout ½ mm, prevention of size reduction of central hole by thermalexpansion or hydrogenation is necessary. The plurality of disks 315 arepreferably placed on spindle 345, as shown, in order to prevent centralhole closing. The coefficient of thermal expansion of stainless steel isabout 17×10⁻⁶/° C. Spindle 345 expands from about 14.9 mm, at about 20°C., to about 15 mm in diameter, at about 350° C. Since magnesium is lessdense than stainless steel, spindle 345 preferably constrains disk 315to expand vertically and radially outward as disk 315 is heated andhydrogenated.

Thermal and internal strain from forced expansion away from spindle 345theoretically reduces absorption of hydrogen near center hole 360 ofdisk 315, approximately within ring 365. Such reduction in absorption isinconsequential since central area of hydride disk 110, including ring365, is preferably not lased. Furthermore, heating is preferablyincremented slowly to allow enough time for thermal equilibrium andexpansion without undue stress. Such slow heating is preferablyaccompanied by slow increases in pressure. Hydrogenating slowlypreferably allows greater absorption of hydrogen gas 150 because buildup of magnesium hydride does not occur near surfaces 346 impedingcomplete hydrogenation.

Pressure is preferably raised to atmospheric pressure with hydrogen gas150 and at least one thermocouple 550, as shown, is preferably set toabout 21.1° C. to establish initial temperature. Small increments oftemperature and pressure preferably are applied preferably over about 6hours to preferably raise pressure to about 35 bar (500 psi) andtemperature to preferably about 350° C. Final temperature and pressureare preferably maintained for about an additional 2 hours.

At least one step motor 554, which preferably can rotate disk 315 atabout 18,000 rpm, preferably comprises at least one axle 552, as shown.Axle 552 is preferably passed into stainless-steel high-temperaturepressure reactor 510, as shown. Spindle 345 is preferably attached toaxle 552, as shown, allowing step motor 554 to spin spindle 345 insidestainless-steel high-temperature pressure reactor 510. Rotation at about18,000 rpm preferably allows additionally between about 700 psi andabout 3000 psi to be exerted radially on disk 315, once initialhydrogenation is complete, and preferably allows a small amount ofhydrogen “over loading”. Step motor 554 is preferably activated to spinspindle 345 and disk 315 at preferably about 18,000 rpm for about 1hour. Afterwards, disk 315 preferably is slowed to a stop and preferablyallowed to remain at full pressure and temperature for about 1 hourmore.

Hydride disk 110 preferably is formed as Disk 315 preferably becomesfully hydrogenated to nearly 100% magnesium hydride preferably with ahydrogen content of about 7.6%. Disk 315 theoretically growsdimensionally during hydrogenation by as much as about 17%, but thesurface area of hydride disk 110 to be lased preferably remains thesame. Hydride disk 110 is highly reactive in air, and great cautionshould be taken in handling and storage.

Magnesium hydride ignites spontaneously in air to form magnesium oxideand water. Such ignition is a violent reaction, which cannot be stoppedby addition of water or carbon dioxide. Therefore, consideration of thepracticality of creating, storing, and transporting hydride disks 110,comprising magnesium hydride, is important. Hydride disk 110 preferablyis stored in at least one inert environment.

Before removing hydride disk 110 from stainless-steel high-temperaturepressure reactor 510, pressure should preferably be allowed to return toatmospheric pressure through release of hydrogen gas 150. Then,optically clear mineral oil 610 (preferably “Sontex LT-100”) ispreferably pumped into stainless-steel high-temperature pressure reactor510, preferably to displace any remaining hydrogen gas 150.Stainless-steel high-temperature pressure reactor 510 may be openedpreferably only after a volume of optically clear mineral oil 610, equalto the interior volume of stainless-steel high-temperature pressurereactor 510 less the volume of hydride disk 110 and spindle 345, hasbeen pumped.

Alternately, hydride disks 110 are preferably stored in a light (−1 to−2 bar) vacuum. When storing in such light vacuum, optically clearmineral oil 610 need not be applied to hydride disks 110. By notapplying optically clear mineral oil 610, other special handling toaccount for optically clear mineral oil 610 may be preferably bypassed.Upon reading this specification, thoses skilled in the art will nowappreciate that, considering such issues as cost, future technologies,etc., other inert environments, such as, for example, inert gasses,other inert fluids, coatings, etc., may suffice.

Optically clear mineral oil 610, as shown, (preferably C_(n)H2_(n+2))preferably comprises a highly purified organic aliphatic hydrocarbon,preferably comprising an index of refraction of about 1.47 and a lighttransmittance of about 0.99972. Optically clear mineral oil 610preferably does not interact with hydride disk 110. Optically clearmineral oil 610 preferably acts as an atmospheric insulator to preventoxidation and static discharge. Upon reading this specification, thoseskilled in the art will now appreciate that, under appropriatecircumstances, considering such things as wavelength of light source,cost, available materials, etc., other atmospheric insulators, such asresins, other oils, solutions, etc., may suffice.

In addition, flow of hydrogen, due to concentration differences, isminimal due to inherently high hydrogen content of optically clearmineral oil 610. Preferably, care should be taken to avoid any moisturecontent in optically clear mineral oil 610, as well as in manufacturingenvironment, when stainless-steel high-temperature pressure reactor 510is opened. Such moisture may cause formation of hydrogen peroxide (H₂O₂)in optically clear mineral oil 610. In addition, ambient air preferablyshould be as dry as possible, also to preferably prevent hydrogenperoxide development in optically clear mineral oil 610. Optically clearmineral oil 610 preferably has a loss of only about 0.028% of lightpassing through. Preferably, optically clear mineral oil 610 has amolecular weight of about 40.106, a flash point of about 135° C., aspecific gravity greater then 0.8, and a boiling point approximately300° C. Hydride disk 110 preferably may now be removed fromstainless-steel high-temperature pressure reactor 510 and preferablyimmediately placed in at least one holding container 600 of opticallyclear mineral oil 610, as shown. Preferably, optically clear mineral oil610 remains around hydride disks 110 to prevent contact with air. Asmentioned, such contact may result in a violent reaction creating amagnesium fire.

FIG. 6 shows a diagrammatic view, illustrating at least one holdingcontainer 600 for a plurality of hydride disks 110, according toembodiment 101 of FIG. 1. Transfer of hydride disk 110 fromstainless-steel high-temperature pressure reactor 510 to optically clearmineral oil 610 in holding container 600 preferably should only beperformed with proper safety apparel and adequate fire suppressionavailable. An understanding of proper handling and methods of fireextinguishing of magnesium hydride is paramount. The informationprovided in this application is not an adequate substitute for propertraining Eye protection should be worn (preferably a welder's mask)because of the brilliance of a magnesium fire. Also, heat and fireresistant clothing should be worn due to the intensity of a magnesiumhydride fire. Sand, in plastic bags, should preferably be available toplace on a fire should one erupt. Tabletops and flooring shouldpreferably be of soap stone or other inert material, not metal or wood.Carbon dioxide (CO₂) extinguishers or water should never be used on amagnesium fire, since such extinguishers promote the reaction.Alternately, holding container 600 preferably maintains a light vacuumfor storage of hydride disk 110, negating need for optically clearmineral oil 610.

FIG. 7A shows a diagrammatic view of at least one mineral-oil removalsystem 700, illustrating removal of optically clear mineral oil 610 fromhydride disk 110, according to embodiment 101 of FIG. 1. When usingoptically clear mineral oil 610, optically clear mineral oil 610preferably is removed from hydride disk 110, using mineral-oil removalsystem 700. The heat of vaporization of optically clear mineral oil 610,comprising about 214 kJ/kg, is particularly important. The moreoptically clear mineral oil 610 left on hydride disk 110, the more powerneeded to efficiently adsorb the stored hydrogen, since optically clearmineral oil 610 left on hydride disk 110 will absorb a portion of theheat generated by coherent light 170.

Mineral-oil removal system 700 preferably comprises at least one diskspinner 710, as shown. Disk spinner 710 preferably comprises at leastone spinner motor 715, as shown. Disk spinner 710 preferably operates inan area of negative pressure. Disk spinner 710 preferably may be adaptedfrom at least one CD drive. To adapt such at least one CD drive, allelectronic components preferably must be shielded from exposure tooptically clear mineral oil 610, preferably by at least one polymer,preferably polyvinyl. Prior to use, hydride disk 110 is preferably movedinto disk spinner 710, as shown, and preferably spun by spinner motor715 to about 24,000 rpm to recover most of optically clear mineral oil610, preferably for reuse.

FIG. 7B shows a diagrammatic view of mineral oil removal system 700,illustrating removal of residual mineral oil 712 from hydride disk 110,according to embodiment 101 of FIG. 7A. Mineral oil removal system 700preferably further comprises at least one residual mineral oil remover717, as shown. Residual mineral oil remover 717 preferably comprises atleast two opposing suction vacuums 720, as shown. After spinning,opposing suction vacuums 720 preferably pump off any residual mineraloil 712, comprising optically clear mineral oil 610, for reuse, asshown. Opposing suction vacuums 720 preferably substantially coverdiameter of hydride disk 110, as shown. 100% recovery, of opticallyclear mineral oil 610, may not be possible without vaporization duringlasing of hydride disk 110. Minimization of vaporization preferablyminimizes energy consumption of the lasing process. Vaporized mineraloil preferably should be collected for ecological and safety reasons.After removing optically clear mineral oil 610, hydride disk 110preferably is passed to disk player 210, as discussed in FIG. 8, forhydrogen adsorption, as discussed herein (See FIGS. 1 & 2).

FIG. 8 shows a diagrammatic view, illustrating at least one hydrogensupply system 800, according to the preferred embodiment of FIG. 1.Hydrogen supply system 800 preferably comprises holding container 600,mineral oil removal system 700 and disk player 210, as shown. Hydridedisk 110 is preferably moved from holding container 600 to mineral oilremoval system 700, preferably for optically clear mineral oil 610removal, as shown. After optically clear mineral oil 610 issubstantially removed, hydride disk 110 preferably transfers to diskplayer 210 for hydrogen adsorption, as shown. After completing at leastone adsorption process, used hydride disk 910 preferably is returned toholding container 600, as shown, for safe storage. Processing of hydridedisk 110 is preferably conducted under negative pressure (about −1 torr)preferably to allow for hydrogen collection and preferably preventingexposure of hydride disk 110 to air.

Unlike magnesium hydride, exhibiting 80% transparency, magnesiumexhibits mirror like opacity, when manufactured as discussed herein.Transparency variation of hydride disk 110 from used hydride disk 910therefore preferably indicates hydrogen content. Such transparencyvariation may preferably be used to distinguish at least one usedhydride disk 910 from such at least one hydride disk 110, and may alsopreferably be used as at least one “gas” gauge 880. At least onetransparency probe 850 preferably polls stored disks 860. Transparencyinformation passes to at least one processor 870 where quantities ofsuch at least one hydride disk 110 and such at least one used hydridedisk 910 are determined. At least one value is then calculated foravailable hydrogen stores and may be displayed as such at least one“gas” gauge 880.

Hydrogen supply system 800 preferably further comprises at least onecondensing tank 810, as shown. Gases released from processing maycontain vaporized mineral oil (when using optically clear mineral oil610), in addition to hydrogen gas 150. Such gases are preferablycollected and preferably pass into condensing tank 810. Condensing tank810 preferably comprises at least one cooling environment at atmosphericpressure. Optically clear mineral oil 610 is not dissociated into itsconstituent elements by vaporization in an anaerobic atmosphere.Optically clear mineral oil 610 is preferably recaptured withincondensing tank 810, as shown.

After condensation of optically clear mineral oil 610 in condensing tank810, hydrogen gas 150 is preferably supplied to hydrogen-driven device830. Alternately preferably, hydrogen gas 150 is pressurized in at leastone pressure tank 820 to at least one atmosphere of pressure, beforebeing supplied to hydrogen-driven device 830, as shown. Hydrogen gas 150supplied by hydrogen supply system 800 preferably maintains supply ofhydrogen gas required by hydrogen-driven device 830 to operate steadily.Pressure tank 820 preferably acts as a hydrogen gas reserve, allowingaccelerated use of hydrogen gas 150, for a limited time, beyond thehydrogen adsorption rate of hydrogen supply system 800. Pressure tank820 may preferably be sized to provide sufficient quantity according toat least one brief increased supply need of hydrogen-driven device 830.

Hydrogen-driven device 830 preferably comprises at least one vehicleengine adapted for using hydrogen gas 150. Such at least one vehicleengine preferably comprises at least one combustion engine, alternatelypreferably at least one hybrid engine, alternately preferably at leastone hydrogen power cell driven engine. Upon reading this specification,those skilled in the art will now appreciate that, under appropriatecircumstances, considering such things as then availability, cost,purpose, etc., other hydrogen-driven devices, such as cooking devices,generators, heaters, etc., may suffice. For application to such at leastone vehicle engine, pressure tank 820 preferably comprises a size ofabout two liters which may hold up to about ½ kg of hydrogen gas 150.Applicant has determined that, under relevant circumstances, anabout-two-liter size of pressure tank 820 allows for about a 30-secondburst of increased consumption for acceleration. After such 30-secondburst, pressure tank 820 may preferably recharge giving, as similarlydetermined by applicant, about a 50-second recovery time.

For hydrogen-driven device 830 comprising at least one typical vehicle,hydrogen supply system 800 should deliver a supply rate of about 1.3kg/hour of hydrogen to maintain better than 50 miles per hour. Thickness144, rotation speed of hydride disks 110, power of semiconductor laserdiode 165, and the number of semiconductor laser diodes 165 should beoptimized to reach such at least one supply rate. If semiconductor laserdiode 165 is too weak, then rotation speed of hydride disks 110 has tobe slowed in order to liberate enough hydrogen. The slowed rotationspeed of hydride disks 110 will then require a plurality ofsemiconductor laser diodes 165 and a plurality of disk players 210 tomaintain an adequate supply of fuel.

Applicant has determined, including by experimentation, that using onesemiconductor laser diode 165 (at about 760 nm) at an operating speed ofabout 2×(about 2.6 m/s) requires about 33 minutes to release about 1.2grams of hydrogen. Using this operating speed requires about 148 diskplayers 210 with about 8 semiconductor laser diodes 165 each to deliversuch at least one supply rate of about 1.3 kg per hour. This wouldrequire an additional 10 kg and 2 cubic feet to accommodate. The totallaser power comprises about 236 watts (0.32 horsepower) and such about148 disk players with disk changing mechanisms would require about 300watts (0.4 horsepower). Preferably, when using a plurality ofsemiconductor laser diodes 165, each semiconductor laser diode 165differs in power proportional to the distance from the center of hydridedisk 110, since actual linear speed is a function of the radius.Multiple semiconductor laser diodes 165 preferably may be replaced withat least one diode laser array, preferably at least one bar laser (thisarrangement at least herein embodying wherein such at least one photonicexciter comprises at least one array of lasers).

By comparison, applicant has determined, including by experimentation,that using another semiconductor laser diode 165 (at about 780 nm) at anoperating speed of about 48× requires only 3 minutes. At about 48×,about 14 disk players 210 with about 8 semiconductor laser diodes 165each delivers such at least one supply rate. Under these conditions,operating hydrogen supply system 800 requires about 0.25 horsepower.

Applicant has determined that the percentage of the power producedneeded to run hydrogen supply system 800, based on experimental findingsand a fuel cell efficiency of about 50%, comprises about one percent.

Applicant has found through testing that this preferred formula(Mg+MgNi) and preferred structure (NiTi—Mg+MgNi—NiTi) absorb hydrogen atmodest temperature and hydrogen pressure. What Applicant found to beremarkable and novel is the effect that UV (100 nm to 400 nm) and IRlaser light (400 nm to 1 mm) have on the sorption kinetics of thematerial. The dielectric created by the hydrogen material (MgH2+Mg2NiH4)(higher insulation), while stacked between layers of a partiallyhydrogenated Nitinol (NiTi) metal material (lower insulation) createsmulti-layers of surface plasmon polaritons. The interface between thelayers gives rise to coupled modes in the metal-insulator-metalheterostructure. The ability to control wave vectors through thesestructures can preferably be attained with geometry, including the holesdrilled in the material, and also preferably with triangular V-groovesin the surfaces of the Nitinol metal. The localized surface plasmons inthe metal nano-particles and near the insulator nano-particles, allowselectromagnetic energy to be confined into a volume less than thediffraction limit. This leads to field enhancement and supports emissiveprocesses which further the effect of the UV and laser light inphoton-molecular interactions. In addition, the preferred structuresselected, and preferred frequencies used, preferably allow coupling ofthe electromagnetic field to lattice vibrations at infrared frequencies,and preferably give rise to localized and propagating surface phononpolaritons. This preferred arrangement preferably provides thatphotonics with phonons at infrared frequencies and plasmonics at lowerfrequencies preferably provide sub-wavelength energy localization,preferably with evanescent waves, and together preferably contribute tothe enhanced sorption kinetics observed by Applicant in themagnesium-hydrogen complexes and structures developed with drilledbeam-channel holes, as described herein, and also with triangularV-grooves.
